I'm using a 0.1 conc iodine and it's quite difficult to see where it is on the miniscus... any way I could make sure it's exactly on the miniscus? How would they do this in a real chemical industry?
this is in no way a really technical or accurate way of doing it but when we were using potassium manganate VII in a titration and we couldn't see the meniscus because the compound was quite a dark purple. Our teacher told us to shine a light through the burette (most of us used our phone screens) and this made it easier to distinguise where the meniscus was.
There probably is a proper way to do it but this is what we used

I had this with 0.02 moldm-3 iodine. T'was pretty annoying at first but you get used to it. My teacher told me she had burettes with fluorescent increment markings at uni (that might answer your question on the industry solution), that'd make it so much easier...
